The Future of Brake Discs
Why reinvent vehicle brakes?
Coated brake discs are setting the standard for reducing particulate emissions from the braking systems of all motor vehicles while providing the necessary corrosion protection for electric vehicle brakes.
Legislation
The Euro 7 emissions standard, expected to take effect in 2025, will require, based on current knowledge, further reductions in fine particulate emissions. This shifts the focus to tire and brake wear.
Environmental Protection
Particle filters are already available to collect and store brake pad and cast iron disc wear directly in the brake caliper. However, this results in additional maintenance work and costs for vehicle owners, and used filters must be disposed of. Ideally, no brake dust should be generated during braking at all. Brake discs equipped with a wear-resistant coating minimize resulting wear over a generally longer service life, offering a dual benefit for our environment.
Electric Mobility
In both battery electric vehicles (BEVs) and hybrids (HEVs), the service brake is used much less frequently and with less force due to the regenerative braking of the electric motor. As a result, cast iron brake discs corrode more quickly under the influence of rain, snow, and road salt. In an emergency stop, this can lead to an unpleasant surprise: poor braking performance initially removes the rust from the braking surface. By the time the brake pad regains full contact with the now-clean disc, it’s often too late. For this reason, automakers are focusing on durable corrosion protection for BEV and HEV brake discs. Stainless steel coatings could also be used for this purpose.
